Noah Feldman is a professor and writer who tries to figure out how to make the government follow the rules; what the rules are that the government has to follow; and what to do if the rules are being broken. In his work, he asks questions like: How can a 225-year-old constitutional blueprint still work? Can you design a new and better constitution from scratch in places like Iraq and Tunisia? What rights do we have, really?

Feldman is the Felix Frankfurter Professor of Law at Harvard Law School and a contributing writer for Bloomberg View. He served as senior constitutional advisor to the Coalition Provisional Authority in Iraq, and advised members of the Iraqi Governing Council on the drafting of the Transitional Administrative Law or interim constitution. He is writing a biography on James Madison, principal author of the Constitution and fourth president of the US; it's forthcoming in 2017.
